(*LeviCivita[mu, nu, rho, si] is an input function for the totally antisymmetric Levi-Civita tensor. It evaluates automatically to the internal representation Eps[LorentzIndex[mu], LorentzIndex[nu], LorentzIndex[rho], LorentzIndex[si]] (or with a second argument in LorentzIndex for the Dimension, if the option Dimension of LeviCivita is changed). LeviCivita[$\mu , \nu  \text{...}$][ $p, \text{..}$.] evaluates to Eps[LorentzIndex[$\mu$], LorentzIndex[$\nu$], ..., Momentum[$\text{p}$], ...].The shortcut LeviCivita is deprecated, please use LC instead!.*)
